,Question 3
Minimum separation from power conductors
Correct Answer
The minimum separation from power conductors that cables must be when in
midspan in an aerial application is 6".
Question 1: According to the National Electrical Code (NEC), what is the maximum
voltage rating typically associated with Class 2 remote-control, signaling, and power-
limited circuits supplied by a source that complies with UL 1310?
A. 15 volts
B. 30 volts
C. 50 volts
D. 100 volts
CORRECT ANSWER: B. 30 volts
Rationale: Under NEC Article 725, Class 2 power-limited circuits are specifically
designed to have voltages typically not exceeding 30 volts (AC or DC) under normal
operating conditions, providing protection against electric shock and fire hazards.
Question 2: Under NFPA 72, what is the minimum required sound pressure level for
public mode audible notification appliances in general areas of a commercial
building?
A. 10 dBA above average ambient sound level or 5 dBA above maximum sound
level, whichever is greater
B. 15 dBA above average ambient sound level, but not less than 75 dBA
C. 15 dBA above the ambient sound level, or at least 5 dBA above the maximum
sound level having a duration of at least 60 seconds, with a minimum of 75 dBA in
occupiable spaces
D. Exactly 85 dBA measured at 10 feet from the appliance
CORRECT ANSWER: C. 15 dBA above the ambient sound level, or at least 5 dBA above
the maximum sound level having a duration of at least 60 seconds, with a minimum
of 75 dBA in occupiable spaces
Rationale: NFPA 72 (National Fire Alarm and Signaling Code) mandates that public
mode audible notification appliances produce sound levels that exceed the ambient
Page 2 of 126
,sound level by at least 15 dBA or exceed the maximum sound level by at least 5
dBA, with a floor of 75 dBA measured 5 feet above the floor.
Question 3: When pulling fiber optic cables in a commercial riser shaft, what is the
primary mechanical limitation that technicians must strictly monitor to prevent
permanent core damage?
A. Torsional twist angle
B. Maximum tensile load (pulling tension)
C. Jacket durometer hardness
D. Minimum operating temperature
CORRECT ANSWER: B. Maximum tensile load (pulling tension)
Rationale: Exceeding the manufacturer's specified maximum tensile load on fiber
optic cables can stretch or break the glass strands, causing microbends,
macrobends, or total fiber fracture, leading to high attenuation or complete signal
loss.
Question 4: In accordance with NEC Article 800, communications cables installed
vertically in a vertical shaft that passes through more than one floor must generally
be listed as which of the following types unless protected in metal conduit?
A. CMR (Communications Riser)
B. CMP (Communications Plenum)
C. CMX (Communications Limited Use)
D. CMG (Communications General Purpose)
CORRECT ANSWER: A. CMR (Communications Riser)
Rationale: NEC Article 800 requires cables passing vertically through floors in a
vertical shaft to be rated as CMR (Riser-rated) to restrict the vertical spread of fire
and toxic smoke between floors, unless enclosed in raceways like rigid metal
conduit.
Question 5: Which of the following fire alarm circuit types is defined under NFPA 72
as maintaining circuit survivability and continuous operation during a fire condition
to ensure communication or control signals are not lost?
A. Class A circuit
B. Survivable pathway / Pathway survivability level
Page 3 of 126
, C. Class B circuit
D. Non-supervised loop
CORRECT ANSWER: B. Survivable pathway / Pathway survivability level
Rationale: NFPA 72 specifies pathway survivability levels (e.g., Level 1 through Level
4) for emergency communication systems and fire alarm systems to ensure critical
notification and control lines remain functional for specified durations during a fire
event.
Question 6: Under Georgia law and contractor licensing regulations, what is the
maximum monetary penalty or administrative action the Georgia State Construction
Industry Licensing Board may impose for unlicensed low-voltage contracting?
A. A verbal warning for the first offense
B. Cease and desist orders coupled with civil penalties up to $500 per violation per
day
C. Mandatory community service
D. Automatic felony conviction without a hearing
CORRECT ANSWER: B. Cease and desist orders coupled with civil penalties up to $500
per violation per day
Rationale: The Georgia State Construction Industry Licensing Board is authorized to
issue cease and desist orders and levy civil penalties (typically up to $500 per
violation per day) against individuals or entities engaging in low-voltage contracting
without a valid license.
Question 7: What is the minimum bending radius specification for standard
unshielded twisted pair (UTP) Category 6 horizontal copper data cable during and
after installation, expressed as a multiple of the cable's outer diameter?
A. 2 times the outer diameter
B. 4 times the outer diameter
C. 8 times the outer diameter
D. 10 times the outer diameter
CORRECT ANSWER: B. 4 times the outer diameter
Rationale: Industry standards (such as TIA/EIA-568) dictate that UTP copper cables
must not be bent to a radius smaller than 4 times the cable's outer diameter to
prevent internal pair untwisting and impedance mismatch.
